JAMES H. MASTERSON, OF COLLEGE POINT,

OSANN COMPANY, A CORPORATION OF NEW YORK.

NEW YORK, ASSIGNOR T0 FREDERICK WORK-HOLDER FOR SEWING-MACHINES.

To all whom it may concern:

Be it known that I, JAMES H. MASTERSON, a citizen of the United States,and a resident of College Point, Queens county, Long Island, State ofNew York, have invented Improvements in Work-Holders for Sewing-Machines, of which the following is a specification, reference being hadto the accompanying drawings, forming part thereof.

This invention has reference to improve ments in work holders for sewingmachines and particularly for such machines adapted to form a group orgroups of stitches.

One object of the invention is to so construct a work holder of thenature herein referred to that it may readily be mounted in and carriedby the button holding jaws of an ordinary button clamp.

Another object of the invention is to so construct a work holder that itmay receive and hold, during a stitching operation, a wire loop adaptedto be engaged by a garment hook.

Other objects of the invention will appear from the followingdescription.

The invention consists in the work holder having means for engaging theloop bar of the loop device. I

The invention also consists in the loop carrier adapted to be mounted ina button clamp.

The invention also consists invsuch other novel features of constructionand combination of parts as shall hereinafter be more fully describedand pointed out in the claims.

Figure 1, represents a side view of the improved work holder as appliedto a sewing machine of well known construction parts of which are shown.

Fig. 2, represents a plan view of parts of the same.

Fig. 8, represent-s a plan view of the loop carrier removed from thebutton clamp, parts being broken away.

T Fig. 4, represents an edge or side view of Fig. 5, represents anenlarged sectional view as taken on line 55 Fig. 3.

Fig. 6, represents a plan view product.

Similar characters of reference designate corresponding partsthroughout.

The main purpose of the present invention is to provide means for soholding and po- Specification of Letters Patent.

Application filed May 21, 1917. Serial No. 189,935.

sitioning two elements or articles in a. sewing machine that saidelements or articles may be secured together by stitches and preferablyso that said elements or articles may be secured together in a novelmanner. One of said elements or articles is a fabric or a part of afabric A, and the other element or article is a wire loop or a memberadapted to be engaged by a garment hook and having the comparativelystraight loop member B, upstanding vterminal eyes or rings C and D whichconstitute bases extending laterally from the line of their member B.Such eyes or rings G and D are similar in construction and are definedby different reference characters merely for the purpose of describingmore definitely the sewing operations.

In addition to the usual stitch forming devices including the needle N,the sewing machine to which this improvement is adapted to be applied isprovided with a suitable work holder mechanism which includes the baseplate 10 having the cloth plate 11 furnished with the comparativelylarge needle passage or opening 12, said cloth plate 11 being sustainedon the bed plate 13 or other suitable and useful member of the sewingmachine frame similar to that shown more fully in my copendingapplication for patent filed May 21, 1917, Serial No. 169,938, to whichreference is made. Said Work holder having the base plate 10 is alsoprovided with the arm 14 capable of movement toward and from said base10 and furnished with the plate 15 having the post 16 to a member 17 ofwhich the usual lifting chain 18 is attached. Plate 15 has the fixed arm19 having the depending tapering end 20 adapted to act as a gage orpositioning element and said plate 15 has also the pivoted springpressed arms 21, 21 having the depending ends 22, 22 constructed attheir inner sides to receive and hold a button or other article. Arms21, 21 are adjusted and secured in the adjusted position by any usualmeans.

Between the ends 22, 22 of the arms 21, 21 is mounted the carrier framehaving the connecting or cross member 27, furnished with the notch 28 toreceive the gage or member 20, and having the side arms 29 and 30adapted to be received by said ends 22, 22 of arms 21, 21 andrespectively having the shoulders 31 and 32 to be engaged by saidalineinent as indicated by line s r-av Fig. .3

With the work in position as shown in. Figs. 1 and 5 the machine isoperated int-he usual manner. and by the relative vibration of the workand the needle the'loops of the stitches S are cast over one side memberof the eye or. ring terminal C.
